SPECIFICATION forming part of Letters Patent No. 581,003, dated April 20, 189'?.

Application filed January 16, 1897. Serial No. 619,402. (N model.)

To all whon/L t may concern.-

Be it known that I, HOWARD E. DYER, a citizen of the United States of America, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Envelops g and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in envelops, and more especially to that class of envelops used to convey registered packages and to be accompanied on the exterior thereof by a letter or card of instructions or receipt-card to be returned to the mailing-office. It is designed to afford a pocket accessible from the outside for the card or letter of instructions. It is specially designed for use in the registered-mail service of the United States, and is substantially an improvement on the envelop at the present time in use in the mail-service of the United States, being the envelop patented to Maro S. Chapman June, 1878, No. 204,422. n

The custom in the mail-service at the present time is to fold the envelop, place the card between the folds, and secure the card therebetween by a cord passing from end to end and side to side and knotted. This is objectionable in several respects. The folding of the envelop at or near the center results often in the folding of the inclosed package and possible damage thereto. It is inconvenient to tie and untie the cord. The receipt-card is liable to become dislodged in transmission. To obviate this objection, I have made a pocket in the outside of the envelop not in communication with the interior thereof and on the side opposite to that designed to receive the postmark and address, or, in other words, on the side opposite to the opening proper to the envelop.

I am aware that it is not new, broadly, to provide an envelop with an external receiptpocket.

In the drawings herewith accompanying and forming a part of this application, Figure l is a plan view of the blank from which, by folding as hereinafter described, the envelop is made up. Fig. 2 is a plan view of the back or side of the envelop opposite the sealing side thereof, showing end of card projecting from the pocket; and Fig. 3 is a transverse sectional view on line X X, Fig. 2, of the completed envelop with a card therein.

The blank consists of a body part A, having a transverse slit B therein, end flaps C and D, and side iiaps E and F, side flap E being provided with one or more supplemental flaps G, and the end iiap D being provided with a supplemental nap I-I. In making up the envelop the end flap O is gummed throughout its whole extent except the portion included between the slit and the outside dotted lines, as shown in Fig. 2, and is folded down and secured by means of said gummed surface to the body part, thus forming a pocket J between the body part and end flap O when the envelop is made up. The other end flap is then folded down, and the supplemental flap H is folded around the end and by means of adhesive substance secured to the opposite side of the envelop. The side flap F is gummed and secured to the end flap D, one or more of the supplemental iiaps G being free. The envelop is then ready to receive the package or letter to be inclosed.

To seal the envelop, the side flap E is gummed and folded down upon the end flap D. The supplemental flaps G are gummed and extend over and are secured to the side flap E, or, if desired, the middle flap G may be secured to end iiap D under the side flap E, thereby strengthening the end flap D at its weakest point.

A locking-nap I maybe secured to the body part at a point at or near the slit adapted to pass over the end of the card K into said slit and between the card and body part. This would be necessary only when extraordinary security was desired, for in all ordinary cases the friction would be ample to prevent the card from being accidentally dislodged. By this arrangement the pocket is on the side of the envelop opposite the address and in no wise interferes therewith. At the same time the package is properly sealed. In use the postmaster at the mailing office inserts a receipt-card in the pocket, and the receiving postmaster withdraws the card, ills out the receipt, and returns it to the mailing office, himself putting a receipt-card in the pocket IOO and forwarding it to the next distributing ofee.

Having thus described 1ny invention und its use, I claiml. Ineregistered-paekage envelop, an open external receipt-pocket between the body part and one of the end flaps, au opening thereto through the body part, a sealed pocket between the end flaps and side flaps for sealing said last-named pocket, substantially as and for the purposes set forth.

2. An envelop consisting of a body part, end flaps one adapted to be secured to the body part and form :t pocket therebetween, the other adapted to extend over the former and around the end thereof, :L sealed pocket between said end flaps, side flaps and un opening through the body purt to said first-named poeket-7 substantially as and for the purposes sot forth.

3. An envelop Consisting of a body part, end flaps one adapted to be secured to the body part and form :L pocket therebetween, the other adapted to extend over the former and around the end thereof, :t sealed pocket between said end flaps, side flaps, an opening through the body part to said i'stmznned pocket and a looking-flap secured to the outside of the body part and adapted to extend over the projecting end of the card and through said slit between the eard and body part, substantially as and for the purposes set forth.

In testimony whereof l affix my signature, in presence of two witnesses, this 13th dayof January, 1897.
